It's 2010, Sunghoon is your classmate, you're "friends", almost in a relationship but it's nothing confirmed. You act like a couple but don't kiss and are not exactly dating. It's complicated...

You're walking on the school court when you feel a ball hitting your head, you turn around and see it is Sunghoon, laughing with his friend, Hyungshin, starts running from you laughing and saying

"SORRY! SORRY!"
